Depends on what you wear. I wear Kuiu Vias, ASAT, Predator Brown Deception, Cabelas Outfitter...I would expect the Gray to work well with those.I'm not sure what color to get either, what do you think will be the most popular color?
And I have to think it would be pretty easy to simply attach some matching camo fabric to the seat if you really wanted to. You could get a neck gaiter or cheap T Shirt and do it yourself. You can get an ASAT Leafy headnet for under $20
